3)
Molar mass of C6H10,
MM = 6*MM(C) + 10*MM(H)
= 6*12.01 + 10*1.008
= 82.14 g/mol
mass of C6H10 = 2.67 g
mol of C6H10 = (mass)/(molar mass)
= 2.67/82.14
= 3.251*10^-2 mol
According to balanced equation
mol of CO2 formed = (12/2)* moles of C6H10
= (12/2)*3.251*10^-2
= 0.195 mol
Molar mass of CO2,
MM = 1*MM(C) + 2*MM(O)
= 1*12.01 + 2*16.0
= 44.01 g/mol
mass of CO2 = number of mol * molar mass
= 0.195*44.01
= 8.583 g
Answer: 8.58 g
4)
Molar mass of O2 = 32 g/mol
mass of O2 = 5.88 g
mol of O2 = (mass)/(molar mass)
= 5.88/32
= 0.1837 mol
According to balanced equation
mol of CO2 formed = (6/3)* moles of O2
= (6/3)*0.1837
= 0.3675 mol
Molar mass of CO2,
MM = 1*MM(C) + 2*MM(O)
= 1*12.01 + 2*16.0
= 44.01 g/mol
mass of CO2 = number of mol * molar mass
= 0.3675*44.01
= 16.17 g
Answer: 16.2 g
